Ocean Energy for a Sustainable Future
The Ocean Battery is a scalable, modular solution for large scale storage of electricity that is produced by renewable sources such as wind turbines and floating solar farms at sea. It is a pumped hydro system in a box that provides utility-scale energy storage of 2 – 10 MWh per unit. The mechanism is based on the technology of a hydro dam, a technology that has proven itself for over a century as highly reliable and efficient.
To store potential energy, the system pumps fresh water into flexible bladders that are deflated by the pressure of the water above our battery. The Ocean Battery is suitable for both newly build and existing wind and floating solar farms.
Discover the unique advantages of the Ocean Battery
Plug & Play Energy Storage at the Source
Our Ocean battery provides storage at the source. This way, we can reduce local peak loads in the network and optimally match supply and demand.
Reliable & Affordable
By applying a proven hydro dam technology, we can guarantee a long lifetime of decades and a high round-trip efficiency. Therefore, our technology is reliable and affordable.
Our battery is highly sustainable, and the storage medium is based on fresh water with biological additives. The construction is designed to act as an artificial coral reef to support flora and fauna.
Energy when we need it and where we need it
Producing renewable energy is crucial to achieve a climate-neutral economy. The energy transition requires a significant change in the energy system. More and more solar and wind turbine parks are being realized onshore and offshore to contribute to a sustainable society. In the coming 10 years, the offshore wind turbine parks will grow from 20 GW to a capacity of 180 GW, a massive growth!
To grow to a system where renewable energy is the norm, the biggest hurdle must be solved: energy storage. At Ocean Grazer, we tap into this huge potential of renewable energy.
